Title: Digital radio communication equipment
Inventor: ITO MAKOTO
IPC: H04L5/16
Filed: 1995-04-19
Abstract: PURPOSE: To suppress a bit error rate by reducing the generation of distortion caused by over-driving at the time of the input of high intense electric field. CONSTITUTION: Transmission and reception are executed alternately through the use of a single frequency. A changeover circuit 5 connects an antenna 4 to a transmission circuit 1 when a first control signal S1 is inputted to a first control input terminal T1 and connects the antenna 4 to a reception circuit 2 when a second control signal S2 is given to a second control input terminal T2. A control circuit 3 decodes a signal inputted from the reception circuit 2 and supplies a transmission signal for the transmission circuit 1. The control terminal 3 gives the first and second control signals S1 and S2 to the first and second control input terminals T1 and T2 in a not linked state to control the changeover circuit 5.

IPC: H01L21/768
Filed: 1990-04-11
Abstract: PURPOSE:To flatten the upper part of a plug consisting of a tungsten film subsequent to an etchback and to improve the reliability of a wiring by a method wherein Al ions are implanted in the tungsten film and an etching rare in the tungsten film is made uniform. CONSTITUTION:An insulating film 2, such as an NSG film, a PSG film, a BPSG film or the like, is formed on an Si substrate 1 by a CVD method and thereafter, a titanium nitride film or a titanium-tungsten film, for example, is formed as a close contact layer 3 by a sputtering method. Then, an implantation is performed, a lamp annealing is performed in an N2 atmosphere, Al is diffused in a grain boundary between a tungsten film 4 and the layer 3 and a gap between the grain boundary and the film 4 is filled with the Al. After that, an etchback is performed on the condition that an etching rate in the tungsten film 4 becomes equal to that in an Al alloy film 5 using chlorine gas and the tungsten film 4 is left only in the interior of a contact hole. Thereby, the upper part of a plug consisting of the tungsten film 4 can be made to obtain a flat form without being recessed the central part of the plug.

Title: Object detector
Inventor: SAKAO HIDEKI
IPC: G01C3/06
Filed: 1994-05-06
Abstract: PURPOSE:To accurately detect the presence/absence of an object by horizontally arranging detecting windows and accurately detecting the distance to the object regardless of the positional deviation of the object. CONSTITUTION:LEDs 9 and 10 are horizontally arranged at a prescribe interval (d) and, at the same time, PSDs 11 which respectively receive light rays reflected from a human body P to be detected are arranged in the middle of the LEDs 9 and 10. A human body P to be detected is alternately irradiated with the light rays from the LEDs 9 and 10 under the control of a control circuit and the distance to the human body P is calculated from the detected values of the PSD 11, and then, the shorter detected distance is judged as the distance to the human body P. Therefore, the presence/absence of the human body P can be always detected with accuracy, since either one of the PSDs 11 detects the accurate distance to the human body P even when the human body P goes out of a detecting area.

Title: Recording medium drive device
Inventor: NAKAGAWA KENZO
IPC: H04N5/225
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To lengthen the life of a recording medium and to secure the safety of writing a data in a user data area(UDA). SOLUTION: The recording medium has the UDA where an actual data is written and a program memory area(PMA) where a management data is written. In the PMA, the number of write repeating times in the UDA, a write ending address AE, the number of life cycles NL and the last address AL, etc., are written. At the time of recording an actual data in the UDA, the write is started from the next address after the AE at the previous recording time (ST21), and after recording until the AL, the write is started from an address 0 again (ST22-ST24), and then the NA is increased by one (ST25). The actual data is evenly written from the first address 0 to the AL in the UDA. When the NA exceeds the NL, an alarm is displayed and the disk is ejected. The write of such an actual data which is out of security of the safety in writing the UDA is avoided.

Title: Scanning optical device
Inventor: MAKINO JUN
IPC: H04N1/04
Filed: 1989-04-14
Abstract: PURPOSE:To obtain the timing of an accurate image write start with compact structure by making luminous flux, propagated in an optical path different from luminous flux for writing, incident on a photodetector after the luminous flux is reflected repeatedly between an optical deflector and a plane reflecting mirror. CONSTITUTION:The plane reflecting mirror 12 is fixed at the position where the plane reflecting mirror becomes parallel to one reflecting surface 12a of a polygon mirror 12 when the reflecting surface comes to right before a write start position, and the mirror is so arranged that the luminous flux different from the luminous flux for writing is made incident on the photodetector 4 from a light source device 3 after being reflected repeatedly between said reflecting surface 12a of the polygon mirror 12 and the plane reflecting mirror 2. Therefore, even when the distance between the light source device 3 and photodetector 4 is short, the light incident on the photodetector increases in deflection speed or scanning speed and the output signal of the photodetector 4 rises sharply. Consequently, the accurate image write start timing is obtained although the constitution is compact.

Title: Mold for ultrasonic welding and ultrasonic welding method by using said mold
Inventor: TENUN MASAO
IPC: B29C65/02
Filed: 1987-04-17
Abstract: PURPOSE:To enable a frame body to stretch a sheet under a strained state, by a method wherein a pinch press surface tilting toward the inside is provided on a pinch press part formed annularly according to a form of the frame body. CONSTITUTION:An end of the circumference of a cylindrical tip of a pinch press part 3a of a horn 3 side situated on the upper part of a pinch press part 4a of an anvil 4 side is in a platelike state due to a gentle curved surface toward the inside, and the curved surface is formed as a pinch press surface S performing pinch press of the fringe of a sheet 1 by coming into contact with the same. Then a frame body 2 is set up within a positioning protrusion 4b of the anvil 4 and the same is pressed by the horn 3 by superposing a netted sheet 1 over the frame body 2. With this construction, as the sheet 1 and frame body 2 are melted at both contacting parts through frictional heat due to an ultrasonic vibration, and the same as, under a state where a lubricant is interposed in-between. Therefore, frictional force between the sheet 1 and frame body 2 is low, the frame body 2 only is shrunk inward due to a horizontal component froce P2 and the netted sheet 1 is welded to the frame body 2. With this construction, when pinch press due to the horn 3 is released, the frame body 2 is restored to the original state, the netted sheet 1 is strained evenly by pulling the netted sheet 1 outward and stretched flat.
